-Subject: [PATCH 20/21] cpufreq: mediatek: Raise proc and sram max voltage for
- MT7622/7623
-
-During the addition of SRAM voltage tracking for CCI scaling, this
-driver got some voltage limits set for the vtrack algorithm: these
-were moved to platform data first, then enforced in a later commit
-6a17b3876bc8 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
-using these as max values for the regulator_set_voltage() calls.
-
-In this case, the vsram/vproc constraints for MT7622 and MT7623
-were supposed to be the same as MT2701 (and a number of other SoCs),
-but that turned out to be a mistake because the aforementioned two
-SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V.
-
-Fix that by adding new platform data for MT7622/7623 declaring the
-right {proc,sram}_max_volt parameter.
-
-Fixes: ead858bd128d ("cpufreq: mediatek: Move voltage limits to platform data")
-Fixes: 6a17b3876bc8 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
